The importance of ferroalloys in the steelmaking process


The importance of ferroalloys in the steelmaking process are those:

Common ferroalloy products include ferrosilicon, ferrochromium, ferromanganese, calcium silicon alloy, etc. Generally, ferroalloys play an important role in deoxidation, purification, cost reduction, and quality improvement in the steelmaking process.

The production of ferroalloys requires a lot of electrical energy. Generally, submersible arc furnaces are used to produce them through carbon heating. Some ferroalloy products with lower carbon content need to smelt the intermediate alloy first and then use metal thermal reduction to produce them. The same ferroalloy product has different grades and alloys. The higher the element content, the lower the content of carbon, phosphorus and other impurities, the higher the price, and the better the steelmaking effect. As the ferroalloy used in steelmaking, appropriate grades of ferroalloy products should be produced according to the requirements of the steel type, thereby reducing the cost of steelmaking. . During the subsequent processing of ferroalloys, it is also necessary to classify the components into shapes with a certain particle size for use. Generally, the particle size of ferroalloys is 10 to 50mm. During the steelmaking process, the components of molten steel and ferroalloys can be evenly fused to cause chemical reactions and reduce losses. Iron alloys must be baked before use, mainly to reduce gases being brought into the molten steel.
